14.11.2 Tool Offset Based on Tool Numbers
Explanation
- Tool pot number output
When a tool number (T code) is specified, the corresponding tool pot
number is read from the tool data file, then is output to the machine as a
tool function code signal (T0 to T31) together with the tool function
strobe signal (TF).
- Compensation based on a cutter compensation value and tool length compensation
value
When an M code for tool change is specified, the cutter compensation
value and tool length compensation value of the previously specified
tool number (T code) become valid. Then, compensation is applied
using the valid compensation values when a compensation command
(such as G43 and G41) is executed.
NOTE
Use parameter No. 2429 to specify an M code for
tool change.
Example)
Tool data setting
N01 G10 L70 ;
N02 T01 P10 K11.0 R12.0 ;
N03 T02 P20 K21.0 R22.0 ;
N04 G11 ;
Compensation based on tool data (when the M code for tool change is M06)
N11 T01 ; : The pot number, 10, corresponding to T01 is output as a code signal.
N12 M06 ; : The cutter compensation value and tool length compensation value
corresponding to T01 become valid.
N13 G43 _ _ _ ; : Tool length compensation is performed using the valid compensation
value (K11.0 of T01).
N14 T02 ; : The pot number, 20, corresponding to T02 is output as a code signal.
N15 G41 _ _ _ ; : Cutter compensation is performed using the valid compensation value
(R12.0 of T02).
N16 G40 G49 ;
N17 M06 ; : The cutter compensation value and tool length compensation value
corresponding to T02 become valid.
N18 G43 _ _ _ ; : Tool length compensation is performed using the valid compensation
value (K21.0 of T02).
